(Cl. 285-16) The invention relates to new and useful improvements in filler nozzles commonly in use in the fueling of storage tanks in airplanes, although adaptable to other tank lillinguses, and it primarily seeks to provide a novel arrangement of a readily mountable and replaceable wear plate means in such nozzle structures. f

Filler nozzles of the character stated are known and are mounted by bringing the fuel outlet end of the nozzle into cooperative relation with the tank inlet and securing means of the bayonet slot type thereon, and turning the nozzle end or a part thereof to effect a secure coupling of the nozzle to the tank inlet. This relative turning of parts, repeated many times, results in considerable wear. While this nozzle and coupler part rubbing and wearing presents little problem in many uses, the nozzles sometimes are in use in sandy locations or places Where abrasive dust accumulations may be encountered, and in such instances the problems of wear are accentuated and part replacements often are diicult and expensive.

Therefore, it is an object of the invention to provide a novel nozzle part arrangement wherein are included wear plate means effective to receive the Wear to which reference has been made and which are subject to convenient replacement at minimum expense.

Another object of the invention is to provide a novel filler nozzlestructure wherein are included an inner sleeve or body subject to being coupled to the tank to be serviced and which carries the wear plate means, and a shell surroundingV and turnable about the sleeve or |body and effective to couple the nozzle to the tank, the shellbeing composed of matching half sections so as to adapt the same for assembly with and removal from the sleeve or body with great facility.

Another object of the invention is to provide in a nozzle of the character stated a thin wear plate means in the form of a split ring subject to being quickly and easily applied to the sleeve or body by twisting apart of the split ends of the ring to receive the. sleeve or body therebetween.

A further object of the invention is to provide a nozzle structure of the character stated wherein the parts are so cooperatively arranged that the split wear plate is engaged by a split ange on the shell and yet the split `of the flange is placed so that it will not pass over and interfere with the wear plate split during turning of the shell in the mounting and dismounting of the nozzle.

A still further object of the invention is to provide a nozzle structure of the character stated wherein a novel key plate arrangement is included, said key plate being spring pressed and displaceable by locking sleeve engagement incidental to the coupler attachment, means being included for holding the key plate against rotative movey'ment relative to the body at all times.

-With the above and other objects in view thatwill hereinafter appear, the nature of the invention will be more Vclearly understood by reference to the following detailed description, the appended claims and the several views illustrated in the accompanying drawings.

In the drawings:

FIGURE 1 is a side elevation illustrating the improved nozzle structure.

FIGURE 2 is a plan view, the off position being shown in full lines and the on position in dot and dash lines.

FIGURE 3 is a vertical cross section taken on the line 3-3 on FIGURE 2.

FIGURE 4 is a part side elevation and part vertical cross section, the section being taken on the line 4-4 on FIGURE 1.

FIGURE 5 is an enlarged fragmentary vertical cross section showing the upper portion of lthe nozzle of FIG- URE 3, the poppet valve being shown in its projected position and the nozzle outlet connected with an adaptor.

FIGURE 6 is a plan view of the wear plate, and FIG- URE 7 an edge view of said plate.

FIGURE 8 is a plan View of the key plate, and FIG- URE 9 an edge view of said plate. A

FIGURE 10 is a fragmentary horizontal sectional view showing the engagement of one of the key plate lugs in one of the receiving recesses.

Referring in detail to the drawings, a tank to which the improved nozzle attachment is connected is shown as provided with a tank housing 5 which is preferably `secured to the bottom wall of the tank. The housing has a liange 7 which may be secured to the tank wall by bolts or other means (not shown), a sealing gasket 8 being interposed for sealing the connection as illustrated in FIGURE 5.

The housing 5 has an inwardly projecting portion 9 having an opening 10 therethrough, and attached to the underside of the portion 9 is an Vannular member 11 having a passage 12 therethrough. The passage 12 is surrounded at its upper extremity by a ared face providing an inclined valve seat 13. The annular member 11 also has a depending sleeve portion 14 carrying readily outwardly projecting bayonet lugs 15 to which the ller nozzle forming the subject ofthe present invention is attachable in a manner to be described hereinafter. The annular member 11 is secured to the housing portion9 by securing means 16, and a vsealing means is interposed at 17.

The passage 12 of the annular member 11 serves as an inlet passage through which fuel may be supplied to the tank, and said pasage is controlled by a valve 1 8 which is spring seated at 19 in a manner well known in the art.

The improved nozzle structure includes an inner housing body or sleeve generally designated 2,0 and 'having provision at 21 for attachment to a delivery line or hose (not shown). The inner sleeve is surrounded by an outer shell which is rotatable thereon and generally designated 22. See FIGURE 3.

The inner sleeve or .body is equipped withbearing 'bosses 23 in which a cross shaft 24 is rockable in the manner clearly illustrated in FIGURES 3 and 4 of the drawings. An actuator crank 25 having a at `abutment portion 26 (FIGURE l) is secured on the outer end of the shaft, and a crank 27 is secured on the shaft Within the sleeve or body 20. The crank 27 is link connected at 28 to a thrust rod 29 on which is mounted 4a valve head 3 0, the same being secured in position asindicated at 31. The valve head 30 is receivable in the cylindrical end portion 32 of the sleeve 20 inwardly of its receiving are 33. The valve 30 carriesl a sealing ring 34 secured thereon `by the cap plate 35, and when the nozzle is mounted in the manner illustrated in FIGURE 5 andthe annular member 11 is slotted at equidistantly spaced points as at 40 for reasons to be described hereinafter.

The valve carrying rod 29 is slide guided as at 41 so that it will partake of movement along the axis of the sleeve 20 in projecting and retracting the valve head 30-35 in the manner previously described.

The inner sleeve or body 20 is provided with an outwardly projecting ange 42 to the surface of which a wear plate 43 is secured in the manner illustrated in FIGURE 5, by equidistantly spaced screws 44. It will be apparent by reference to FIGURES 6 and 7 of the drawings that the wear plate is radially split at 45 and is equipped with angular clearances 46 inwardly of the split. The wear plate preferably is thin and formed of hard anodized aluminum, and by reason of the provision of the radial split 45 and the clearances 46 projecting angularly and inwardly therefrom, it is possible to readily twist Hex the wear plate in mounting `the same about the body or sleeve 20 beneath the outwardly projecting flange 42 thereof.

The screws 44 which secure the wear plate 43 against the underface of the shell flange 42 are provided with upwardly projecting end extensions 47 which are engageable in the downwardly opening slots 40 provided in the sleeve 14 depending from the annular member 11, thereby to hold the sleeve 20 against rotation relative to said annular member when the nozzle structure has been mounted in the manner illustrated in FIGURE 5. The flange 42 is equipped with a plurality of equidistantly spaced pockets 48. It will be apparent by reference to FIGURE that the pockets 48 overlie the wear plate 43, and each pocket carries a compression spring 49, the purpose of which will become apparent as this description progresses.

The outer shell generally designated 22 is composed of matching half sections 50, as best shown in FIGURES 1 to 2. The shell half sections are equipped with half pockets 51 in which to receive angularly disposed handles 52 when the half sections are secured together as indicated at 53; One half section 50 is provided with a radial lug projection disposed to overlie the at portion of the actuator handle 25 when the nozzle has been applied to the tank as indicated in FIGURE 5 but not turned to fully mounted position. The lug 54 is so placed with relation to the handle 25 that it will prevent turning of the handle and projection and opening of the valve means 30-35 until the nozzle structure has been turned to its fully and securely applied position illustrated in FIG- URE 5.

At its top end extremity, the shell 22 comprising the assembled half sections 50 presents an outwardly directed radial annular flange 55 which engages with the undersurface of the wear plate 43 in the manner illustrated in FIGURE 5. A mounting ring 56 is secured at 57 on the flange 55 and projects upwardly therefrom, said ring terminating upwardly in a well rounded outwardly turned portion 58. The ring 56 includes an inwardly directed securing flange portion 59 which is notched at equidistantly spaced points, as at 60, to receive the lugs on the sleeve 14. The ring 56 also is notched or recessed at 61 to receive radially projecting, equidistantly spaced lugs 62 provided on a key plate 63 which overlies the compression springs 49 in the manner illustrated in FIG- URE 5. The key plate is illustrated in detail in FIG- URES 8, 9 and 10 and includes inwardly opening, equidistantly spaced edge notches 64 disposed to receive the upward projections 47 on the wear plate securing screws 44 for at al1 times locking the rotary position of key plate 63 with respect to sleeve 20. It will be apparent that the springs 49 normally project the key plate 63 upwardly so that in the uncoupled condition of the nozzle it will engage under the ring flange 59 with its lugs 62 engaging in the recesses 61 to lock the outer sleeve 22 in its rotary position on sleeve 20. Handle cannot be moved to open the nozzle with outer sleeve 22 in this locked condition while the nozzle is uncoupled from tank housing sleeve 14.

It will be apparent by reference to FIGURE 5 that when the nozzle is to be mounted the valve carrying end thereof is brought into cooperative relation with the tank housing 5 and the upper end extremity of the body or sleeve 20 is inserted into the sleeve 14 depending from the annular member 11, the sealing ring 36 coming into sealing contact with the seating shoulder 39 as shown in FIGURE 5. During this insertion of the upper end extremity of the sleeve 20, the lug projections 15 carried by the depending sleeve 14 will be passed through the receiving notches 6) and the handles 52 will be utilized to turn the shell 22 in the making of the bayonet slot connection well known in the art. In the making of this connection, the key plate 63 will be depressed against the action of the springs 49.

Depressing of key plate 63 removes lugs 62 from recesses 61, thus unlocking outer shell 22 kso that it may be rotated with respect to inner shell 20. Such rotation causes bayonet lugs 15 `to pass under ange 59 out of register with slots 60 whereby the nozzle will be secured to member 11. Rotation of key plate 63 with respect to outer shell 22 continues to be prevented at this time by engagement of pins 47 with notches 64. Rotation of the outer shell 22 upon inner sleeve 20 for coupling the nozzle to the tank housing 5 is limited by engagement of key plate lugs 62 with shoulders 65 before the split line 66 of the shell halves 22, 'which follow the line of projection of the handles as shown in FIG. 2, can pass over the split of the wear plate. Thus at no time during coupling or uncoupling of the nozzle do these split lines cross or pass over each other.

In the particular arrangement shown, principal Wear will be occasioned at the shell flange or shoulder portion 55 because of the fact that hard anodized aluminum is employed in the making of the wear plates 43. When the wear plates become worn they may be removed by removing the shell halves and screws 44 and twisting apart v the free ends of the wear ring. Clearances 46 in the wear A plate facilitate passing the wear plate over flange 42 when twisting the same .for this purpose when mounting or removing the wear plates.

While preferred example disclosures of wear plate and other part arrangement is made herein, it is to be understood that variations in such part structures and arrangements may be made without departing from the scope of the invention as defined in the appended claims.
